Abstract

PURPOSE: To improve the load prediction accuracy and the roll gap setting accuracy by calculating a rolling load and a rolling reduction position from temperature, plate thickness and plate width of a material to be rolled, measured in front of a finish rolling mill, and the heating quantity by an edge heater.
CONSTITUTION: A thermometer 10, a plate width meter 11, a plate thickness gage 12 and an edge heater 13 are provided in front of a finish rolling mill, and plate temperature, plate width and plate thickness are inputted as data of a finish rolling mill setting computer 30. A plate thickness calculation is determined by a load allocation calculating system 19, load allocation data is inputted to a rolling load calculating system 20, and the plate temperature is derived by a difference calculation from a plate head part center surface temperature. A rolling load calculation derives roll flatness by an expression by using the derived plate temperature. In such a way, load calculations at the time when the edge heater is used, and at the time when it is not used can be discriminated and calculated, and the load prediction accuracy and the roll gap setting accuracy are improved.
